Describes three easy biology experiments and the steps involved.

Simple homemade batteries are described that can be made from items found in the home or school lab. These experiments help students understand how to wire them up, the origin of current, voltage and power, as well as the chemistry that...

In this electronics science fair project, students will make a simple dimmer switch and investigate the relationship between the resistance in the circuit and the amount of light produced. The Science Buddies project ideas are set up...

Here is described a simple process to 'put a voice on a sunbeam' and transmit it over a distance. It is a fascinating example of amplitude modulation of light using sound vibrations. It then describes how the modulated light is detected...

Make a simple wind instrument and use it to experiment with pitch.

An activity that will have you questioning which is in control, your eyes or your brain? This activity has students constructing simple paper tubes to investigate how the eyes work.

Create a simple device to see how a force is exerted on a current by a magnetic field. This activity shows how an electric motor can be made with this force.

An engineering design project to use simple materials to make an instrument to mimic the sound of a swarm of bees.

Understand the concept of resonance to allow you to cause two pendulums to swing in an identical cycle. Pendulum are constructed from simple materials like string, pencils, paper clips, and pennies.

In this lab activity, students are required to write a procedure to be followed in a simple lab process and record the results they get from following that procedure. They then exchange procedures with another lab group, which will have...

This experiment and video demonstration shows how students can break up water into hydrogen and oxygen gas with a simple electrolysis device.

Described is a simple low cost home-made device that converts the radio wave energy from a mobile phone signal into electricity to light an LED. No battery or complex circuitry is required. The device can form the basis of a range of...

Discover how Gregor Mendel uncovered the key principles of inheritance using a simple, familiar system: the pea plant. Learn about Mendel's life, his experiments, and his legacy.
